Claims. or. 296-401) This is a division of application Serial No. 265,450, filed Mar. 15, 1963. This invention relates to a vehicle body and particularly to a body of the kind employed for collecting refuse, including cartons, cans and the like as Well as garbage. In such bodies means have been provided for moving longitudinally of the body to compact the collected cartons, cans and other refuse from time to time, and also to discharge the contents of the body.

Compaction bodies have usually been employed to collect refuse from factories and other commercial establishments and are too long and too high to be practical for use in residential driveways and yards. And they have been too expensive for such.

It is an object of this invention to provide such a body which will be practical for residential use.

Another object of the invention is to provide such a body of improved structure, which will be durable and at the same time economical to build.

Another object is to provide such a body of reduced height which will nevertheless have a large capacity in proportion to its height and length.

Gther features of the invention reside in many details of structure. The invention will best be understood if the following description is read in connection with the drawings in which FIGURE 1 is a perspective view of the frame of the body,

FIGURE 2 is a side elevation of a complete body,

FIGURE 3 is a front elevation of the body shown in FIGURE 2,

FIGURE 4 is a top plan view, partly broken away and in section, looking down on the forward portion of the structure shown in FIGURE 2 including the compacting blade,

FIGURE 5 is a perspective view partly broken away and in section, showing the structure of the compacting blade and the means for supporting it and keeping it disposed at right angles to the side walls of the body.

FIGURE 6 is a vertical section taken on line 6-6 of FIGURE 2,

FIGURE 8 is a vertical section taken on the line 88 of FIGURE 7,

FIGURE 9 is a detail transverse sectional view taken on the line 9-9 of FIGURE 2, showing how the support tract for the compaction blade is itself supported,

FIGURE 10 is a top plan view of the structural detail shown in FIGURE 9,

FIGURE 11 is a detail view partly in longitudinal vertical section taken on the line 11-11 of FIGURE 3 showing how one end of the cylinder and piston combination which moves the compaction blade is mounted at the front end of the track on which the blade is mounted, and

FIGURE 12 is a detail view partly in longitudinal vertical section taken on the line 1212 of FIGURE 6 showing how one end of the cylinder and piston combination which opens and closes the body rear end or cover is mounted at the rear end of the track on which the blade is mounted.

In the embodiment of the invention shown and de 3,Z@Z, i5h Patented Aug". 24, 1965 scribed herein the body comprises a frame constructed of channel members supporting sides, floor and top of sheet metal. The way these parts are interrelated constitute features of the invention. It will be noted for example that the two level floor provides a body which may be wide in relation to its height. Or stated another way, it makes it possible to keep down the height of the body while compensating in Width for the reduction in height.

It will also be noted that the top is formed of strips of sheet metal extending transversely of the body and interrelated and interconnected with one another and with vertical frame members and the sheet metal sides in ways which are features of the invention. Other features are the way the track beam, on which the compacting blade is mounted, is supported inside the body; the Way the cylinder and piston combinations for moving the blade and for opening and closing the rear end cover respectively are mounted at opposite ends of the track; the way in which the whole body is secured on a truck chassis; and the structure of the blade and the way it is attached toits cylinder and piston combination making it possible to move the blade all the way to the front end of the body, thus melting it possible to utilize the full length of the body, which in turn makes it practical to use bodies of reduced length.

Referring now to FIG. 1, it wil be seen that the frame comprises a bottom having the outside longitudinal members ill and 12 respectively comprising the portions 19a and ltic interconnected by the upwardly curved wheel cover portion 30b, and the portions 12:: and 12c interconnected by the upwardly curving wheel cover portion 1212; the

longitudinal members

14 and 16 disposed in parallel relation between the

outside members

11 and 12, and spaced apart a distance which is the conventional distance between longitudinal members of a truck chassis, for mounting the body on a chassis as will be explained, and a number of cross members 18 extending between the

outside members

10 and 12 and interlocked with the

members

14 and 16.

Vertical members

29, 22 and 24 extend up from bottom member it and

vertical members

26, 28 and 30 extend up from bottom member 12, in' opposed relation to members 2t), 22 and 24.

The members 20 and Z6, 22 and 28, and 24 and 30 are interconnected at the top by

members

32, 34 and 36 respectively.

The longitudinal members 3'7 are sides of the frame.

The floor is made with two levels. The main portion 33 rests on, and is welded to, the

bottom members

14 and 16 and the portions of the cross members 13 which are spaced from the lateral margins of the bottom a distance equal to the depth of the wheel housings defined by the wheel cover portions ltib and 12b which in use extend over the rear wheels of the chassis. The lateral marginal portions 4%? and 42 of the floor are offset above the main portion 58 a distance equal to the height of the wheel cover portions liib and 12b and extend over the wheel covers respectively. A unitary pieces of sheet metal may be bent to form the floor, or it may preferably be made of three pieces with inner edges of the marginal strips bent down and then inwardly to provide an inner edge portion at the height of the center portion of the floor and adapted to overlap and be Welded to the main center portion.

Transverse ribs 43 welded to the sides respectively we tend under the

marginal portions

40 and 42. of the floor to strengthen them.

The sides 4-4 and 46 are formed by attaching sheet metal to the inside surfaces of

upright frame members

26, 22 and 24 and 26, 28 and 3% respectively, and the provided along the formed of'strips 48 of sheet The ends'of member 90 disposed on the beam 86) at its front end strips 48'are bent down over; and welded to, the sheet metal sides. Where the ends' of the strips encounter

upright frame members

20, 22, 24, 26, 28 and 39, the upper edge portions of the frame members are cut away or offset asat 49 to receive the berit-over.ends of the stripsv which are thus engaged between thesheet metal sides and the inner surfaces of the offset faces of the upper ends of the upright members of the frame.

The strips are interengaged along their abutting edges by means which provides increased strength. One edge of each strip isfolded upwardly in an inverted U bend 50 and the other edge is bent up to form a single upwardly extending flange 52. The fiange' 52 of one strip is force fitted into the U-bend 56 of the abutting strip,

thus forming a top of interlocked strips which is strengthened by the transverse ribs 54 comprised by the

members

50 and 52; y I V As stated above, the

bottom frame members

14 and 16 are spaced apart to register with and rest on the longitudinally extending

members

56 and 58 respectively of a truck chassis. The body is secured on the 'chassis by the clamp means shown in FIGS. 7 and 8. The floor 33 of the body extends over the

frame members

14 and 16. Pairs of bolts 60 and 62 are welded to opposite sides of

spacing members

64 and 66 which are welded to opposite faces of

members

14 and 16. The bolts of each pair'extend down below the

chassis members

56 and 58 respectively, and are interconnected by a'cross member and at right angles to the beam.

The other end of the cylinder and piston means 84 is pivoted on the cross pin 92 supported between the side walls of a housing 94 projecting rearwardly of the body from the main portion 96 of the blade 76. The lower end of the cylinder and piston means 84 is thus offset rearwardly of the body from the main portion 96 'of the blade. This arrangement'is of importance because it enables the means 84, when acuated hydraulically by known means, to draw the blade to the extreme front end of the body. 7 V V The blade comprises the main portion 96 which rests on the rear edge portion of a base channel member 98.

' members 14 and 16'on which the floor portion 38 rests.

68 which extends under the chassis support member and may be raised up against the under surface of the chassis support member'by tightening the

nuts

70, 72 on the bolts. By unscrewing the

nuts

70, 72 and removing the cross members 68 from the pairs of bolts the body can be quickly disconnected from the supporting chassis.

. In the body as illustrated in FIG. 2, the upper portion of the space between the upright frame memb'ersZtl, 22

and26, 28 is not covered with sheet metal, leaving openings W the lower edges of which may be defined by the members or sills 74 extending between members '20, 22

and 26, 28 respectively. The refuse'is loaded into the body through the openingsjW. From time to time itlmay be pushed toward the rear of the body and compacted by a compacting blade indicated generally by the numeral 76, which is constructed as will be described. In FIG.

2 blade 76 is shown in full lines at the extreme front of the body in position to move toward the rear of the body, and to compact refuse loaded into the body through a space or window W." It is also shown in dotted lines in aposition near the rear end of the body.

The blade 76 is mounted on a trolley 78 comprising rollers which rest on the oppositely extending lower flanges of an} beam 80 which thus defines a track. The I beam extends under the top of the body along its longitudinalmid-line and is supported by the top 'cross frame members-'32, 34 and 36 to which it is welded through slots 82 prov ided in the portionsof the top strips which are disposed between the cross frame members andthe beam.

The I beam 80 is tapered upwardly adjacent its ends a and one end of a telescopic cylinder and piston combination 84 of'known kind is pivoted just beyond the front end of the beam on a cross pin 86; extending between downwardly extending portions of twop'arallel pieces of sheet metal which are extended rearwardly and bridged across thetop, thus forming a hood 88 which is welded to the'top of the I beam at its tron-tend where it is not covered by a top strip 48, and is also slotted on its sides to engage and be supported by the short channel Vertical strengthening ribs 19% extend up from member 98 in front of member 88 and are interfitted with and strengthened by a horizontally extending member 102 projecting forwardly, i.e. toward the front end of the body, from member 88. p

The housing 94 is triangular, the side 95 of which, i.e. the-top 95 of'the housing 94, is inclined toward the rear of the body. An apron comprising portions 104 on either side of the housing inclines forwardly from the main portion 96 of the blade to the lower level portion 38 of the floor and each portion hasa cutout 106 in its lower edge bridging the tongue or

rail members

108 and 110 which project up from the flo or portion 38 and are disposed in parallelfdirectly above the bottom frame The apron'members are supported on the inclined rear faces of the pairs of

vertical'members

112 and 114 which are cut out on top'to engage thebase member 98 and exto the top of. the raised floor portions 40and 42 respectively. The rearwardly inclined surface 95 of housing 94

andthe apron portions

96 and 108 have different angles of inclination but they an have aligned lower edges which extend beyond the rear end of the body when the blade is moved to its rearmost position. i

The cover 118 for the rear end of the b ody is hinged along its top edge by a series of two-part hinges 120, one leaf 122 of each of which is interfitted with and welded to the top cross member 36 at the rear end of the body frame, and projects rearwardly from and at right angles to member 36, and the other leaf124 of which is attached to the top portion of the'cover. The cover is dish shaped, curving outwardly from the rear end of thebody to increase the capacityof the body when it is in closed ing means'may be provided for locking the cover in closed position The cover may be raised and lowered by telescopic cylinder and piston means 128 of known kind, shown herein in FIG. 2 withone endpivoted' on a cross pin 190 mounted within a bracket 132 depending from the'rearend of beam and the other end pivoted on the pin 134 supported in the bracket 136 on the inside ofcover'118. r

The structure disclosed herein provides a strong body which is economical and may be made of a size suitable for servicing private homes. i
